Preparation

For Crab Salad
Heat oil in heavy large skillet over medium-high heat. Add shallots and ginger and sauté until tender, about 4 minutes. Add apple, zucchini, both bell peppers and carrot and sauté until tender but not brown, about 5 minutes. Remove from heat. Cool to room temperature.

Mix crabmeat, mayonnaise, 2 tablespoons chopped chives and sauté vegetables in large bowl to blend. Season to taste with salt and pepper. (Can be prepared 1 day ahead. Cover and refrigerate.)

For Sauce:
Combine tomatoes, cilantro, vinegar, garlic and cayenne in blender and puree until almost smooth. Gradually add oil and blend until sauce is thick. Transfer to medium bowl. Season to taste with salt and pepper.
